FractalFly — third-party verifier

This page is written from the point of view of someone who is not us. It loads only two things: the hosted SDK, and public data over the API. It does not touch our repository, and it does not trust our server's numbers — it recomputes the canonical state root locally and compares.

FractalFly is a platform, not a chain. (what that means)

Cell-type names are vocabulary-relative: see the group ↔ vocabulary map for the name we use, the literature name and the hemibrain name of every group (and why a cell count must not be compared across vocabularies).

The same SDK + API serve four connectomes — malecns-v1.0, banc-v888, flywire-v783 and larva-v1; this page pins malecns for a stable baseline. See GET /v1/datasets.

Full developer entry point (60-second quickstart, the /v1 API reference, licences, and what we do not claim): developer guide. We do not publish an npm package — the SDK is served from this site and every file is listed with its sha256 in /sdk/PROVENANCE.json.
